Wartość spiralnej tomografii komputerowej w diagnostyce tętniaków aorty brzusznej

Bibliogr. s. 34

Background: Civilization progress and achievements o f medicine makes the human life longer. The exposure on vessel injuring factors such as smoking and improper diet is still growing. For those reasons the number o f abdominal aorta aneurysms also increased. Early detection o f this pathology, its therapy and follow up considering the most sophisticated diagnostic methods is very important. Material/Methods: In years 2000-2002 2989 helical computed tomography (HCT) examinations of the abdomen were performed in Dolnośląski Ośrodek Diagnostyki Obrazowej. In 173 patients (141 M and 32 F) aneurysms of abdominal aorta have been found. From this group 127 (101 M and 26 F) were patients of Surgical Ward o f our hospital. 73 (63M and 10 F) underwent the surgical operation of prosthesis implantation. 13 persons (11M and 2 F) w ere primarily qualified for endovascular stent-graft implantation, in 7 male this procedure was performed. In 159 patients AAA was primarily diagnosed in ultrasound (USG) examination (100%). In 10 cases additional MR examination was performed. In 13 patients qualified for stent-grafting we also performed DSA. Results/Conclusions: USG examination revealed high sensitivity in establishing aneurysm diameter. HCT is characterized by significantly higher sensitivity and specificity in evaluation of renal and iliac pervasion, in comparison to USG. HCT allows for detection of concomitant pathologies and complications. HCT is necessary before stent-graft implantation and in the follow-up. There is no significant prevalence of MR over HCT. It should be performed in cases with doubtful renal arteries location, or when HCT is contraindicated.
